SPECIFICATION forming part of Letters Patent No. 293,592, dated February 12, 1884.

Application filed November-14, 1883. (No model.) I

York, have inven'ted certain new and useful ImprovementsinRailway-Rail Locks, of which the following is a specification, reference betwo clamps, F F, are slipped over it.

ing had therein to the accompanying drawings.

My invention relates to a mode of connecting and holding the rails of street-railways, and its object is not only to bind the rails to the sleepers, but to support their ends in such manner that an even running-surface will be obtained and maintained in all cases.

To enable those skilled in the art to make and use my invention, I will proceed to describe its construction and mode of using it.

I11 Figures 1 and 2, which are a perspective and cross-section, respectively, A represents one of the sleepers of a street railway. This sleeper is cut away upon its upper.

side, and crosswise of it, so as to form two depressions, 0 representing the surface of the upper one, and d that of the lower.-

a a represent the shoulders of-the upper depression, and or those of the lower.

B represents a metallic plate,which,is made the width of the sleeper, and just long enough to fit between the two shoulders a a, its thickness being equal to the depth of the said shoulders a a, so that when it rests upon the surfaces 0 c at each end it will be flush with the upper surface of the sleeper. This plate is securely fastened to the sleeper at each end by bolts orlspikes; but before being fastened These clamps, which are made of suitable metal, are made flat for near the width of the sleeper, and then theirends are turned upward and then partially downward in a semicircular manner, to fit around the curved sides of the plate B and the flanges of the rails D D.

x :1: represent the shoulders of the lower cut away portion of the sleeper. The depth of these shoulders is about or just equal .to the thickness of the fiat portion of the clamps, so that when the clamps rest uponthe surface 11 the under side of the plate B rests upon the upper of the clamps. The fit of the clamps between the plate B and the sleeper is not so close but that it may be moved in its bed 1ongitudinally of the plate and sleeper when necessary. When rails are to be laid down, the clamps are moved to one end of the opening in which they are held. The rail is then placed in position so that its end will rest upon the plate B at. or about its center. Both of the clamps are then slipped over it. The next rail is then laid down so that its end will abut against the first one, and then one of the clamps will be slipped over it.

makes a smooth continuous road.

The clamps may be held in place by a flat piece of wood inserted in the aperturebetween 1 them, or by any other suitable means.

The rail, generally speaking, is an ordinary center-bearing rail in shape; but the clamps may bemade to fit the flanges of any shaped rail.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

In the construction of a street-railway fastening for rails, the sleeper A, cut away crosswise to form shoulders at a. andac 90, and surfaces 0 c andd d,.in combination with the plate B, the clamps F F, and the rails D D, substantially as and for the purpose set forth.

- In testimony whereof I affix my signature in presence of two witnesses.
